I visited them last year, just after they moved to the new (huge) place Sth of Boston. I wanted a part quickly so went to collect, found them great to deal with. I thought they were setting up a shop in the front of the warehouse, not checked, but if so, and you're not a million miles away I'd definitely pop and see them.
As already mentioned, it's always best to try before you buy, especially helmets. Other option obviously is to try one locally and then purchase on the web, though many dealers will haggle if you try, and it's good to support ya local shop. You never know when you'll need em.
Re-wet weather gear. I'm tempted by some ex army goretex leggings on a local market for £20. 100% waterproof and they have full-length zips down the outside so easy to pull on over boots etc. Bargain, so long as you don't mind the Action Man DPM look.
